ABSTRACT Conventional unbonded elastomeric bearings (ULNRs) are cost‐effective but prone to sliding during earthquakes due to their limited shear deformability. Unbonded Steel‐Mesh‐Reinforced Rubber Bearings (USRBs) offer a solution with increased deformation capacity.

Nonlinear vibration isolators with asymmetric stiffness
A vibration source is commonly coupled to a receiving structure by a vibration isolator. A key trade-off in the choice of vibration isolator is the requirement for a wide frequency range of isolation without excessive static deflection.

Comparison of new Design Guidelines for Composite Cylindrical Shells prone to Buckling [PDF]
Currently, imperfection sensitive shell structures prone to buckling are designed according to the NASA SP-8007 guideline, from 1968, using its conservative lower-bound curve.

Programmable crack dynamics engineering enables flexible strain sensors with high linearity
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

ABSTRACT Vibration isolation has long been a critical area of research, with the design of isolators based on the mechanical properties of Euler buckling beams representing one of the primary approaches. Traditionally, the focus has been on utilizing the negative stiffness characteristics of a post‐buckled Euler beam in parallel with positive stiffness

Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored
